RubyMotion is a revolutionary toolchain for iOS app development. With RubyMotion, you can quickly develop and test native iOS apps for the iPhone and iPad, combining the expressiveness and simplicity of Ruby with the power of the iOS SDK. "RubyMotion iOS Development Essentials" is a hands-on guide for developing iOS apps using RubyMotion. With RubyMotion, you can eliminate the complexity and confusion associated with the development of iOS applications using Objective-C. We'll begin from scratch. Starting by installing RubyMotion, we'll build ourselves up to developing an app that uses the various device capabilities iOS has to offer. What's more, we'll even learn how to launch your app on the App Store! We'll also learn to use iOS SDK classes to create application views. Discover how to use the camera, geolocation, gestures, and other device capabilities to create engaging, interactive apps. We'll develop stunning user interfaces faster with the XCode interface builder and make web apps by using WebView. We'll then augment applications with RubyMotion gems, doing more by writing less code and learn how to write test cases for RubyMotion projects. Finally, we'll understand the app submission process to push your app to Apple's App Store With "RubyMotion iOS Development Essentials", we will learn how to create iOS apps with ease.

RubyMotion gems

Use of gems is based on the programming practice of Don't Repeat Yourself (DRY), which states that when some piece of code is ready to use and is available, why bother working on it again. The RubyMotion community may be very young right now, but it already has some amazing gems that make a lot of tiring tasks pretty easy. Some gems even target challenging functionalities in a very simple manner.

In this chapter we will cover the following RubyMotion-flavored gems:

  • Teacup

  • BubbleWrap

  • motion-addressbook

Teacup – say goodbye to Xcode and XIB files!

Designing a UI for iOS apps is a tough job, especially for developers who have worked previously on easy-to-learn-and-implement web technologies. Teacup is a gem that will make your life really easy. Teacup augments your ability to quickly design and style the views of your RubyMotion application; you can easily create layouts while keeping your code DRY.

Let's create an application and learn how easy it is to use Teacup:
